Around move 30, Lc0 evaluation is close to 2.00 (see eval graph on the right) but the game ended in a draw.

My impression of Lc0 has always been that when it wins, the win is frequently interesting, because it's found some move or line or play that was not obvious. But when it loses, it is usually because it had some terrible error, much like a normally strong human player might blunder.
